[Dspace-tech] ChineseAnalyzer not work in DSpace 4.0

[badboy]

we install  DSpace4.0 on RHEL6.5, and set  the dspace.cfg  like this:

search.analyzer = org.apache.lucene.analysis.cn.ChineseAnalyzer

we meet the error when run #ant fresh_install

 FATAL org.dspace.search.DSIndexer @ anonymou s:no_context:no_search_analyzer:search.analyzer=org.apache.lucene.analysis.cn.Ch ineseAnalyzer 

just as the same as https://jira.duraspace.org/browse/DS-1170

in dspace.conf, if set
search.analyzer = org.apache.lucene.analysis.cn.ChineseAnalyzer

if will fail with #ant fresh-install .....

If I don't set .ChineseAnalyzer before install, ant build successful, and then I edit the dspace.conf
set it to use ChineseAnalyzer, same error message will got when use #dspace index-init

How to do this?

Thanks  in advance!

Hi Chenhe,

DSpace 4.0 uses Lucene 4.4.0. The ChineseAnalyser packaged in this version
does not have a method with the signature of init(Version), so this
error occurs.

According to the api document of ChineseAnalyser, this class is deprecated
and using "org.apache.lucene.analysis.standard.StandardAnalyzer", which has
the same functionality, is recommended instead.

How about trying this class as the value of "search.analyzer" property?

Regards,
Keiji Suzuki
